Informasi distribusi kepadatan stok dan komposisi ikan demersal sangat penting untuk diketahui sebagai bahan masukan guna keberhasilan pengelolaan perikanan. Untuk itu dilakukan penelitian yang bertujuan untuk mengetahui komposisi, kepadatan stok dan sebaran sumber daya ikan demersal di Laut Cina Selatan. Penelitian dilaksanakan pada Mei sampai Juni 2015 dengan menggunakan scientific echosounder BIOSONICS DT-X dan frekuensi 120 KHz. Untuk verifikasi data akustik terutama komposisi jenis dilakukan pengoperasian trawl. Hasil penelitian menunjukkan komposisi jenis ikan demersal di Laut Cina Selatan meliputi 147 spesies dari 55 famili. Stratifikasi komposisi dikedalaman 20-30 m, 30-40 m, 40-50 m, 50-60 m, dan 60-70 m masing masing didominasi oleh ikan dari famili Leiognathidae, Lutjanidae, Nemipteridae, Tetraodontidae, dan Serranidae. Estimasi kepadatan stok sumber daya ikan demersal di Laut Cina Selatan berkisar antara 0,16 – 2,85 ton/km2 dengan rata-rata kepadatan 1,05 ton/km2. Information about density distribution and composition of demersal fish stocks is very important to be known as an input for the success of fisheries management. Current research aimed to determine the composition, stock density and distribution of demersal fish resources in the South China Sea. The research was conducted in May to June 2015 using scientific echosounder BIOSONICS DT-X and frequency of 120 KHz. Trawler sampling was done to verify the acoustic data, especially for species composition. The results show that the species composition of demersal fish in the South China Sea consisted of 147 species of 55 families. The stratification of the composition at the respective depth of 20-30 m, 30-40 m, 40-50 m, 50-60 m and 60-70 m, were dominated by fish families of Leiognathidae, Lutjanidae, Nemipteridae, Tetraodontidae, and Serranidae. The estimated stock density of demersal fish resources in the South China Sea ranged from 0.16 to 2.85 tonnes/km2 with the average of 1.05 tonnes / km2.

Abstract A deep-water coral forest, characterized by slender and whip-shaped bamboo corals has been discovered from water depths of 1200–1380 m at the western edge of the Xisha (Paracel Islands) area in the South China Sea. The bamboo corals are often accompanied by cold-water gorgonian “sea fan” corals: Anthogorgia sp. and Calyptrophora sp., as well as assemblages of sponges, cirrate octopuses, crinoids and other animals. The coral density increased toward the shallower areas from 24.8 to 220 colonies per 100 m2 from 1380 m to 1200 m water depth. This is the first set of observations of deep-water bamboo coral forests in Southeast Asia, opening a new frontier for systematic, ecological and conservation studies to understand the deep-coral ecosystem in the region.
